INTERFAZ GRAFICA (EN MATLAB)

PROGRAMACION AVANZADA

Introduccion

La interfaz gráfica de usuario, conocida también como GUI (del inglés graphical user interface), es un programa informático que actúa de interfaz de usuario, utilizando un conjunto de imágenes y objetos gráficos para representar la información y acciones disponibles en la interfaz. Su principal uso, consiste en proporcionar un entorno visual sencillo para permitir la comunicación con el sistema operativo de una máquina o computador.

Habitualmente las acciones se realizan mediante manipulación directa, para facilitar la interacción del usuario con la computadora. Surge como evolución de las interfaces de línea de comandos que se usaban para operar los primeros sistemas operativos y es pieza fundamental en un entorno gráfico. Como ejemplos de interfaz gráfica de usuario, cabe citar los entornos de escritorio Windows, el X-Window de GNU/Linux o el de Mac OS X, Aqua.

En el contexto del proceso de interacción persona-computadora, la interfaz gráfica de usuario es el artefacto tecnológico de un sistema interactivo que posibilita, a través del uso y la representación del lenguaje visual, una interacción amigable con un sistema informático.
